(Haganai: I don't have many friends (original creator))


The anime adaptation of the youthful romantic comedy novels written by Yomi Hirasaka—the author of Haganai: I Don't Have Many Friends—is finally here!


Every day is full of fun. But something is missing.

"My life would be amazing if only I had a little sister. Why don't I have a little sister...?"

These are the musings of little sister-lover and novelist Itsuki Hashima, who only writes works featuring little sisters. Around him gather a number of unique people: genius author/pervert Nayuta Kani, female college student Miyako Shirakawa, illustrator Puriketsu, and the brutish tax accountant Ashley Ono. Each of them hold their own worries, but live their peaceful daily lives while writing novels, playing video games, drinking alcohol, and filing their tax returns.

Itsuki's younger brother Chihiro watches over Itsuki and his friends. However, Chihiro has a big secret...

It's time to start this youthful romantic comedy filled with geniuses, normal people, and weirdos that will make you laugh and touch your heart!


Itsuki Hashima

Voice: Yusuke Kobayashi

A little sister-lover who strives to create the ultimate little sister not yet seen by man in the world of fiction. He seems like he has lots of confidence, but is actually quite sensitive, and while he seems simple, he's actually fairly complicated. And, though he appears to be twisted, he's actually a pretty good and honest guy.

Chihiro Hashima

Voice: Nozomi Yamamoto

Itsuki's little brother. He's extremely skilled at cooking and cleaning, and is always up to the challenge of taking care of his big brother Itsuki who lives alone.

Nayuta Kani

Voice: Hisako Kanemoto

A junior author of Itsuki's who respects him deeply. She's a genius author who was able to become a top-level selling author in the industry almost instantly after her debut. All her actions are based 100% on her love for Itsuki.

Miyako Shirakawa

Voice: Ai Kakuma

A classmate of Itsuki's from college who has continued to be friends with him even after he quit school. A perfect representation of the modern youth who struggles with romance, friendship, and her own dreams.

Haruto Fuwa

Voice: Satoshi Hino

An author who has been writing around the same amount of time as Itsuki. He excels at self-producing his own work, with his self-produced anime is doing quite well. He appears to be an eloquent handsome young man, but he hides a passionate secret in his heart.
